Tow printing and dyeing device based on textile processing

Abstract

The invention discloses a tow printing and dyeing device based on textile processing. The tow printing and dyeing device based on textile processing structurally comprises a printing and dyeing box, an electric control box, brackets, a roller and a tow discharge port; the brackets are welded to the printing and dyeing box; the tow discharge port is formed between the brackets and the printing anddyeing box; the electric control box is mounted on the brackets; a movable port mechanically connected to the roller is arranged between the two opposite brackets; the tow discharge port is provided with a feeding cylinder, a filament splitting plate piece, an expansion and closing piece, a slideway, a telescopic bottom shaft and a supporting base inside the printing and dyeing box; the top end ofthe filament splitting plate piece penetrates into the feeding cylinder; the expansion and closing piece is fixed to the bottom of the filament splitting plate piece; the expansion and closing pieceis connected with the telescopic bottom shaft through the slideway in cooperation with the bottom end of the expansion and closing piece, the telescopic bottom shaft is mounted and fixed with the supporting base; the tow discharge port is vertically arranged in the printing and dyeing box, and tows are vertically fed, so that the tows can be uniformly distributed into each pad dyeing board slot incooperation with the filament splitting plate piece in the feeding cylinder, and the problem of poor chromatic aberration due to uneven dyeing caused by separation in bundles and difficulty in printing and dyeing is solved.

Description

technical field [0001] The invention relates to the field of textile processing, in particular to a tow printing and dyeing device based on textile processing. Background technique [0002] Tow refers to a basically untwisted long chemical fiber bundle formed by a large number of continuous filaments that are cut into short fibers or made into chemical fiber strips by stretching. A large number of single-strand filaments are assembled into tows. In the textile processing process, the existing technology for cotton tow printing and dyeing generally adopts the pad dyeing method. In continuous pad dyeing, the tows are bundled and immersed in the printing and dyeing solution. However, due to the extremely short time of continuous dyeing and padding, and the entanglement of bundled cotton tows, it is difficult to separate, so that the dyeing cannot be balanced, resulting in the problem of color difference in the edge. Contents of the invention [0003] In view of the above pro...

However, due to the extremely short time for continuous dyeing and padding, and the entanglement of bundled cotton tows, it is difficult to separate, which makes it impossible to balance the dyeing process, resulting in the problem of side-to-side color difference
